Application led May 11,

My invention relates to room heaters, and the` objects of my invention are: first, to provide a novelly constructed heating core for utilizing the 'greatest amount of heat possible for indirectly heating air for heating purposes; second, to provide a heating core for heaters of this class whereby the gases of combustion from a burner are forced to take a circuitous path from one end of a shallow casing to the other and in whlch'the gases ofcombustion are substantiallypocketed and forced downwardly by incllned baiiles; third, to provide a heating core 1n which the side walls thereof are heated to a high -temperature by a minimum of balile construction within the core'- fourth, to provide novelly constructed baA es-` and a no vel arrangement of the batlies relative to the side walls of the core; fifth, to provide a heater of this class in which a large heatedl area 1s exposed to air passing through t-he heater; sixth, to provide aheater of this class which may be positioned on the floor of a ro0m,

supported on the side wall thereof, or built into the wall, if desired; seventh, to provide, as a. whole, a novelly constructed heater for heating rooms; and, eighth, to provide a heater of'this .class which is particularly l simple and economical of construction, durable, efficient and which will not readily deteriorate. f

Withthese and other objects in view, as will appear hereinafter, my inventionconsists of cert-ain novel features of construction,- combination and arrangement of parts and portions, as will be hereinafter described in detail and particularly set forth in the appended claims, reference being had to the accompanying drawings and to the characters of reference thereon which form apart of' this application in which:

Like characters of reference refer to simi- 1927.- serial No. 190,619.

lar partsl andportions throughout the several views of the drawings.

The heater, shown in Figs. 1 and 2, is adapted to be used for heating rooms and is adapted to be moved about in the room, as desired. This heater is supported on a base 1 which forms the lower portion of the heating core casing 2. Around the casing 2 is positioned lthe enclosing casing or housing 3 for directingl the air against and around the heating core.

The casing 2 of the core is relatively wide and high, but very shallow, that is, of little depth from front to rear. At the upper or air heating portion of the casing2, are provided bailles 4 which extend inwardly from the opposite narrow end walls toward the opposite end walls in staggered relation relative to the-adjacent baflies, and are spaced at'their inner ends from said opposite end walls. Said batlles are also inclined downwardly from the end wall of the casing 2 with which. they are connected, thus substantially creating pockets at the under sides of t-he baflles near the portions secured to the end walls.` Thus, they hot gases of combustion from the burner pass through the heating core in al circuitous path and into and out of the pockets, it being noted, however, that any only those of high temperature. The cross section of the baffles are substantially channel Shaped, as shown best in Fig. 2, essen tially for two reasons, namely, to permit expansion of the baffles transversely without distorting the outer walls and .also to direct ss gases pocketed within the core are the gases impinging against the lower sides of the bailles against the side walls of the casing. Positioned below and spaced from the lower end of the lower bail-le, is a heat distributing bailie 5 whichl extends preferably the full length of the core and is provided with perforations 5a`to permit the gases of combustion from the burner 6, positioned immediately below the same, to pass upwardly through the baiile along the whole of its length. The baille 5 is also preferably corrugated longitudinally to prevent distori tion from expansion and also to provide means for directing the hot gases toward the end of the burner at which the outer end of the lower baffle is connected. The burner 6 is,preferably positioned at theone end of the core below the bae 5 near which end the end of the lower bathe 4 terminates so that the greater portion of the heat is distruction in Figs. 3 and 4 is built into a buildrected upwardly past the lower baie 4. Below the burner 6 is provided a longitudinal partition 7 which extends the full length of the core andv is provided with perforations 7 for distributing air uniformly to the combustion chamber. The lower end of the base 1, which forms a part of the core, may also be provided with aA partition 8, as shown. The sides and ends of the base 1 are preferably provided with perforations 1a for admitting air to the combustion chamber through the partition 7. The burnt gases of combustion V,are discharged from the upper end of the heating core through a flue 9 which may be directed either 'upwardly or to the side, said iiue 9 being connected with the casing 2 at the Vend thereof at which the upper end of the upper baiile terminates with the one end wall of the casing 2.

The casing or housing 3, which ma consist of a sheet metal housing covere with asbestos and a thinouter covering of sheet metal, is spaced at all sides from the heating core and is supported relative thereto by spacers or brackets 10, it being noted that the outer housing 3 is spaced from the floor and, therefore, provides a large lopening for the admission of the air to be heated. The air enteringl the housing 3 between the front side of the heating core and the front wall of the housin 3 impinges against the fron-t side wall o the casing 2 and then passes into the room through the opening 3 at the upper portion of the front side of the housing `3. The air enterin the housing 3 at the ends passes u ward y and thence forwardly throu h t e opening 3, whilethe air passing into t e housing 3 at the back portion thereof, passes upwardly, impinging against the back wallzof the casing 2, thence over the upper end of the latter and out through the opening 3u. At the front side of the housing 3 over the opening 3, may be provided a screen or suitable grating 11, if desired.

The heater in the modified form of coning wall. The base is omitted in thisl modiiication and theI heating core casing 2, as

well as the outer housing 3, supported directly on the wall and the settings 12 on the wall. The Wall for this purpose is open, receiving air from below, preferably throu h the sill of the wall. In this modifcation,t 1e4 outer housing 3 is preferably open at its opposite'side, that is, if the rooms at the opposite sides of the wall are to be heated by the same heater. Within the heater, at the opposite sldes ofthe core casing 2, are provided shutf ters 13. The shutters at each side are rovided with arms 14 which are connected y a rod 15, one of the arms .being provided with a control member' 16 whereby all of the shutters at one side may be simultaneously act-uated for either admitting air to the particu- A,lar room or shutting o' the air or heat. The

vent 17 in this modification is preferably directed upwardly through the wall for directing the gases of combustion to the atmosheie. p In the modification shown in Fig. 5, the heater is supported in any suitable manner on the wall of the. room to be heated. The heater for this purpose may be similar to that shown in Figs. 1 and 2 without the base, taking in the air directly from the room. The lower end, however, may be closed, as shown in Fi 5, and airsuppiied thereto fromJ the outsi e through a duct 18 which may pass upwardly through the wall, as in the structuresv illustra-ted in Figs. 3 and 4. In this modification, the burnt gases may be directed backwardly through the vent 9 into a flue 19 for directing the burnt gases of combustion to the atmosphere.

Though I have shown and described a particular construction, combination and arrangement of parts and portions, and certain 'modifications thereof, I do not wish to be limited to this particular constructiomcombination and arrangement, nor to the' modifications, but desire to include in the scope of my invention the construction, combination and arrangement substantially as Yset forth in the appended claims.
